To aill'whom it may concern:

it knownthat I, Joan F. Srnnm, of Allegheny county, Pennsylvania, a citizen of the United States, have invented certain new and useful Improvements in Passenger Car Understructures, of which the following is a full, clear, and exact de scription, reference being had to the accompanyi-ngdrawings, in which like reference characters refer to like parts, and in which- Fignre 1 is a plan view of a portion of a car tmderstructure embodying the present invention; Fi the line 2- -2,

2 is a sectional elevation onl ig. 1; Fig. 3 is a longitudinal vertical section on the line 33, Fig. 2; and g. 4 is. a vertical section on the line 4-4,

An object of the present invntionli's to .provide a car understru-cture with great :cars.

i the king pin" and drawbar strength and comparatively small number of parts, especially adapted for use in passenger A specific object of the present'invention .is to provide a structure permitting the use of continuous center sills, that is, ce fer sills running from end sill to end sill, or through the car bolsters. s

A further specific. object of the present in vention is-to prov dc animproved bolster center. casting forming a combined center sill supportv and stiflener and 3 housing for Referring now in detail to the drawings,- 1 represents'the center sills.

2 is a bolster center casting-having a cenperforation 2* extending throughout its height to receive king pin 3. Casting 2 is iprvided with lateral fianged'webs or extensi s 2*, the flanges of said webs or exten Sims 2* being shaped to fit the peculiar con- "tour or shape of the center sills 1. Webs or extensions, 2 are riveted or otherwise se- .'cured to center sills 1, and thus the casting 2 forms a stiffener or spacer for the center sills 1. lateral extensions 2 which extend beneath center sillsl to support same and which, 1n conjunction with-the flanges of the; extensions 2",, form recesses receiving. the bases of center sills 1. E2stensious"2 are a1soex+ tended beyond the? rmed for the center sills 1 to form or. arings for the heels of the diaphragm, bolster arms or extensions 4 forming with the tie members Casting 2 is also provided with the bolsters or the car. Diaphragms 4 are flanged, their webs facing each other and their flanges extending in opposite directions. These flanges are bolted or otherwise secured through extensions 2.

2 is a recess formed in the casting 2, of semi-circular shape with flaring sides. Re-

between; the extensions 2", and below the center $1115 1, although the same may be of "any suitable shape and location to serve its "housing the anchored end of the drawbar (not shown). Casting 2 is especially reinforced at 2 below and back of the recess 2 to materially assist in the transference of landing and pullingstresses from the casting 2 to the bolster.

As stated before, the bolster comprises, in addition to the center casting 2, oppositely extending members consisting of flanged .diaphragms 4 with their flanges extending outwardly. The bolster also comprises an upper continuous-tie member 5, perforated at 6, at its center, to receive the king pin 3. Tie member 5 is secured at its outer'end to an angle running along the upper edge of the side sill 7. The bolster is also provided with a lower tie member 8, perforated at 9 to receive the king pin '3 and continuous across the car. Tic member 8 is bent dowri at, each end and secured to side sill 7. Lower tie member 8 is shownsas qfa width substfi' tia-l-ly equal to th-edistancebetween the outer edges of the diaphragmsa; interposed between the iiiaphragms 4: and the center sills 1 are filler plates 10 extending beyond the vertical plane of the; edges of the upper tie member 5. Y 4

11 is the center bearinthe lower tie member 8 a secured in place through means of bolts'12. Of course the center bearing plate 11 is perforated to receive the kingpin 3.

1.3 represents corrugated sheet metal, or metal with an uneven surface, extending 'transverse the car and riveted to the center sills and overlapping the edges of the upper tie member 5 to which it is also riveted.

sills or struts riveted to transoms 15 and bolster diaphragms 4 and to which the corrugated metal 13 is also riveted or secured.

16 are metal clips secured to the upper tie iunction which is that of sustaining and.

plate shaped to fitl l are longitudinal intermediate sectional cess 2 is shown-in the drawings as located I v i l l nember 5, of suitable number and location and having wings spaced from the surface 01 the upper tie member 5.

17 represents the flooring of the car or suitable substance or con'iposition which is applied in a plastic form so as to become embedded in the recesses in the metal sheeting 13 and embedded beneath and around Elie clips 16 so that said flooring is securely .ied to the umlerframe.

18 is a longitudinal corrugated wooden flooring strip extending centrally over the flooring 17 throughout the length of the car from platform to platform.

19 re. )resen s a t'aein of wooden blocks '52. i on i l l l l l l l l t l i arranged about the king pin 3 to form a 3 recess covered by a plate Qt). Facing; 19 is a depth equal to the depth of the corrugated flooring strip 18. The flooring 17 may be of smtable extent and preferably extendsi entirely across the car between the inner lining (not shown).

inp; a recess therein below the plane of said center sill in combination with a hing-pin passed through said perforation and a draw bar held in said recess by said lting pin.

In a car understrueture comprising a center sill and a bolster i'i'iemliier, a perforated eenter casting having a recess therein below said center sill in combination with a king pin passed through said perforation and a drawbar held in said recess by said king pin.

(i. In a car tmderstructure comprising a center sill and bolster mtanber, and a center castinghaving a recess below said center sil': all secured together with bolster tie menu bers extending above and below said center asting in combination with a lrinepin passed through said center casting and a drawbar held in said recess by said kin; pin.

7. in a car nnderstl'ucture. a perl'orattal center castinghaving a horizontal recess in following is what I claim as new therein and desire to secure by Letters Patent:

1. In a car umlerstrm-ture comprising a center sill. a perforated center casting recessed to receive said center sill, a king pin passed through the perforation of said castm and a drawbar carried by the king pin and said sting.

2. ln a car uuderstrm-lure comprising a center sill a perforated center astine' rcce sed to receive said center sill and having combination with a king pin passed through liavmg thus described my invention the 5 said perforation. a drawbar held in said re cess by said kin; pin, a perlorattal tie m mber extending beneath said casting; and secured thereto. and a center bearing plate be u *ath said tie member and secured to said casting.

S. in a car understrurture comprising a center sill and a bolster member of greater depth than said center sill, a center rusting i extending: beneath said ccnteF sill and bolwtci member and tie members above and below a second recess in combination with a king 3 pin pa sed through said pcrl'oration and a drawbar held in the second of said recesses by said lung pm.

o. in a car uinlerstructurc. a center eastingdaavin; a vertical perforation therein and a llOllZOliittl recess in combination with a] lung pin pas ed through said pertoratioin and a drawbar held in said by said king pm.

4.. in a car umlerstrtn-ture comprising a center sill, a perforated center casting havsaid casting for tying said parts together.

9. in a car understructure, a perforated P011101 fl I-l' tl' semi-circular recess with flaring sides in combination with a lun pin passed through said pert'oratirm and a drawba -held in said recess by said hing pin. The foregoing; specification signed at Mt Rees ltoclts. Allegheny county, ii ennsyl'nmia. this second day of July. 1908.
